Very nice!

Man, do I love planetary gearing, and to have it all visible like that is awesome!

Can we see some more?

Thanks for your kind remarks. I designed and developed it for a machine shop class. Students get to make the parts from metal donated by a local screw machine company. They personalize theirs as far as cyl. and head colors and take it home. A lot of the guys give them to their Dads for Christmas(when built during Fall term). I am "popnstart" on Utube for other interesting gadgets. ;D

kustomkb: this is the remnants of planetary used in 2006 collegiate mini-baja car competition. May seem a little excessive but this competition is notorious for broken sprockets, chains, spindles, u-joints, etc . You name it and it has broken and as you all know its hard to break a planetary. Thanks. ;D

Are you interested in selling a set of your plans for that engine? I know I would be willing to buy a set.

Friends, there are really no "plans" for this engine as this project is drawn with Autocadd/Inventor, imported into Mastercam, pick a line or a hole, the prototype machine,or the CO2 laser depending on the parts you need and VOILA!! Sorry.
